Claim 2
Dependent Claim
59 words
A hardenable composition which consists essentially of (1) an acrylate and/or a methacrylate monomer, wherein the monomer contains more than 50 wt. % of acrylate and/or methacrylate, (2) more than 0.5 wt. part of a hardener consisting essentially of diisopropylbenzene dihydroperoxide and (3) more than 0.01 wt. part of a hardening accelerator to 100 wt. parts of total monomers.
Claim 3
Dependent Claim
18 words
A hardenable composition according to claim 1 wherein three components are stored in a form of mixture thereof.
Claim 4
Dependent Claim
21 words
A hardenable composition according to claim 1 wherein the acrylate and/or methacrylate is admixed with diisopropylbenzene dihydroperoxide and a polymerization inhibitor.
Claim 5
Dependent Claim
18 words
